Use when designing and documenting the systematic literature search for a Psychological Bulletin review or meta-analysis — databases, search strings, grey literature, deduplication, and a PRISMA-compliant records flow. Builds a reproducible search; it does not screen or code studies.

Systematic Search Strategy (psychbull-literature-search-strategy)

A Psychological Bulletin synthesis stands or falls on its search: it must be systematic, exhaustive, and reproducible, and all systematic reviews must conform to PRISMA. The goal is that an independent team could re-run your search and recover the same pool. This skill designs and documents the search; eligibility decisions and coding live in psychbull-inclusion-and-coding.

When to trigger

  • Designing the search before screening begins
  • A reviewer asks whether the search was exhaustive or reproducible
  • Building the PRISMA flow counts (identified → screened → eligible → included)
  • Updating the search before resubmission

What an exhaustive search covers

  1. Multiple databases, not one. At minimum APA PsycINFO, plus MEDLINE/PubMed, Web of Science, Scopus, and discipline-specific sources (ERIC, EMBASE) as relevant.
  2. Controlled vocabulary + free text. Combine thesaurus terms (APA Thesaurus / MeSH) with free-text synonyms; use Boolean logic and field tags deliberately.
  3. Grey literature & publication-bias mitigation. Dissertations (ProQuest), preprints (PsyArXiv), conference programs, registries, and author contact for unpublished/in-press data — to limit the file-drawer problem before the bias analysis ever runs.
  4. Backward & forward citation chasing. Reference lists of included studies and prior reviews; forward citations (cited-by) of key papers.
  5. Supplementary tools. Google Scholar as a supplement (not a primary database, given non-reproducible ranking).

Documenting for PRISMA / PRISMA-S

  • Record, per source: the exact search string, the database/platform and date searched, and the number of hits. This is the PRISMA-S standard.
  • Track the flow: records identified → duplicates removed → titles/abstracts screened → full texts assessed → studies included, with counts and exclusion reasons at each stage.
  • Save the raw exports; deduplicate in a reference manager (Zotero/EndNote) or screening tool (Covidence/Rayyan) and log the dedup count.

Anti-patterns

  • Searching only one database, or only published, peer-reviewed work (biases the pool)
  • Reporting "we searched the literature" with no strings, dates, or counts
  • A search that cannot be reproduced because the strings were never recorded
  • Letting search scope drift silently from the registered protocol without noting the change
  • Skipping grey literature, then being surprised by publication-bias findings

What search referees verify at the APA flagship

A Psychological Bulletin synthesis lives or dies on whether an independent team could rebuild its study pool. Reviewers at the APA's flagship review journal apply an explicit search bar:

Search expectationPassDesk-reject / major-revision trigger
Database breadthPsycINFO + several others + discipline sourcesA single database, usually PsycINFO alone
Strings recordedPer-source string, platform, and date logged"We searched the literature" with no strings
Grey literatureDissertations, preprints, author contactPublished peer-reviewed work only
Citation chasingBackward and forward, documentedNone; pool is whatever the keywords returned
PRISMA flowCounts and exclusion reasons reconcileNumbers that don't add up to the included k

Worked vignette — documenting the search

Illustrative counts only. The self-affirmation synthesis (final k = 42) builds its PRISMA flow this way under this skill's rules:

  • Databases: PsycINFO, MEDLINE, Web of Science, Scopus, and ERIC, each searched on a stated date with its exact thesaurus-plus-free-text string recorded per PRISMA-S.
  • Grey literature: ProQuest dissertations and PsyArXiv preprints searched; authors of 11 in-progress trials contacted, yielding 3 unpublished datasets — narrowing the file drawer before bias diagnostics.
  • Citation chasing: backward (reference lists of included studies and two prior reviews) and forward (cited-by of the 5 anchor papers) added 7 records the keyword search missed.
  • PRISMA flow: 2,310 identified → 1,640 after dedup → 1,640 screened → 188 full-text → 42 included, with exclusion reasons tallied so the final box equals the analyzed k.

Referee pushback → venue-specific fix

  • "The search isn't exhaustive." → Add the missing databases and grey-literature sources; document author contact for unpublished data.
  • "There are PRISMA gaps." → Supply per-source strings, dates, and hit counts, and make the flow diagram reconcile end to end.
  • "This search can't be reproduced." → Record and deposit the exact strings so an independent team recovers the same pool; treat Google Scholar as a supplement, not a primary source.
